    Did the search, looked at the Big Chart, yet no numbers pop out for Foma 100 5x7 and 8x10 to be done rotary style in Pyrocat HD. Other developers sitting around here are WD2D+ , Diaxtol, and Rodinal.

    This was shot at E.I. 50 and E.I. 100.

    Any starting points for times/ dilutions? Any experience using WD2D+ in a rotary tank?

    I use a lot WD2D+ on my jobo. It's excellent (for me...), different color stain than Pyrocat, less fog than PMK, and very forgiving.
    Tri-x (200) at 10 / 12 minutes (for 35mm to 8x10)
    Efke 25 : 6/8 minutes.
    I like bullet proof neg by the way... :smile:
    I use the same time when using Pyrocat, works fine.

    Tim, I have used it recently in a Beseler drum and motor base. I use a time of 81/2 min, @72 F, 2.5+2+100 processing for plt/pld printing (EI of 50). I found the times very close to Efke PL100 IMO.

    I am a great fan of Wimberley's developer. I have done some amazing APX100 4x5s in this soup. I used an inversion method though, it's just like roll film only different.

    I ran a 5x7 Arista Ultra 100 sheet through WD2D+ rotary last night, 9 minutes. If it's correct, and I won't know till I print it, it looks like it's all stain. This will have some getting use to...

    5x7 Efke 25... tonights experiments.

    Thank you for the response. I will go out tomorrow and shoot a couple more sheets of this stuff and do some experiments with the Pyrocat. If I remember correctly, you go for a slightly higher conrast for Plt/pld but that it should be hidden within the stain if I want to print normal silver paper.
